I have a feeling that the disposal of Sparlock was an emergency situation which had to be dealt with IMMEDIATELY before demons exited the toy's plastic body and wreaked havoc amongst other inanimate household objects, e.g. blender, vacuum, ottoman. You could only imagine the destruction.
Breakfast of Champions is right, Blondie. In fact, in the film, poor little Caleb does imagine the destruction. It's pretty wholesale. The house virtually implodes, all because of him.
If I had never researched on the internet or had many misgivings of my own, and if I'd never been exposed to evil Elderettes and bullying, crassly stupid elders, that little film on its own would have stopped me ever having anything to do with the JW lunacy.
